Ludovic Marie fe7df463fa Play with friends: bound handshakes and the relay's first line in time, cap relay connections
A read timeout restarts with every byte, so a peer trickling one byte at
a time could hold the host's 8 handshake slots (or relay threads) for
hours. The host's openings and the relay's first line now end after 10 s
in all; the relay closes connections past RELAY_MAX_CONNECTIONS (4096).
The docs say what happens to a router mapping when the game crashes.

Horizon documentation

To play, use the launcher; the project site is playhorizon.dev. These pages are for developers.

Build and run

  • Build from source: your own copy of the game, resource preparation, cargo run.
  • Native client: options, controls, the dedicated server, horizon-ctl scripting, packaging, architecture.
  • Graphics: the Simple and Advanced graphics settings, the graphics benchmark and what it measured.
  • Extras: optional zoom, minimap, FPS and keystroke overlays and auto-reconnect, all off by default.
  • Launcher: installs, updates and starts builds; its CLI and MCP server; releasing it.
  • Opt-in data collection: the consent, exactly what is sent, how it is stored and sent.
  • Menus: the title, world list, create world, multiplayer, options and pause screens share the launcher's design tokens and fonts (crates/horizon-theme), drawn by ui_theme over a live frozen backdrop (game/backdrop.rs, blurred and graded by post.rs). Options → Interface → Menu style switches to vanilla's screens (Classic, kept in horizon.txt; HORIZON_MENU_STYLE=horizon|classic overrides it, and scripted runs default to Classic). Title (webm), worlds, options, pause.
